i'm sorry you were feeling homesick...but you'll be home soon, right? i hope you feel better!
as for love, i know that expressing interest can be hard...but like i said in a comment to clay, it's always good to know where you stand with the person, and you can't really know unless one of you takes the first step and tells the other ones how he or she is feeling. also, i don't think you should let summer come without figuring things out...i mean, what if you grow apart during the summer, and then wonder forever what might have been? but that's just my opinion without knowing the details...you'll have to fill me in on what's up over there.
